Overview

Description

Power system protection is one of the most important aspects of the electrical power industry. Without protection, any stem fails. So it is imperative that safety and protection be given utmost importance to avoid catastrophes.
This course is designed to help students to understand the fundamentals of electric power protection, so that they can choose appropriate protective devices/measures for different components, interpret different protection systems in their plant and also detect short-comings. Simple calculations can be performed too.
Most important of all, they can improve the safety of the site by making better decisions on system protection.
